Objetivo

Al-killed type steels are used for the production of enamelling grade steels. To obtain a low fish-scale susceptibility of the Al-killed steels and good drawability properties, the main requirements are high temperature strip coiling and annealing in open-coil box. Though various types of enamelling sheet steels have been developed, it is difficult to produce sheet steels that combine deep drawability and good enamelling properties. The project intends to deal with the following objectives: optimise a new enamelling interstitial free steel produced by continuous annealing process line and prepare new measurements and quality control systems for the fish-scale susceptibility evaluation in enamelled, interstitial free, steel.
